This method of book digitization allows you to scan an entire book by fanning through the pages. It uses a high-speed camera that captures 500 frames per second to get a good look at each page. Processing software isolates each pages, analyzes any curve in the paper due to the flipping, and smooths out the image for better optical character recognition results. The greatly reduces the time it takes to digitize a book, even compared to setups that automatically flip pages.

LEGO Book Scanner

December 17, 2009 by Mike Szczys 10 Comments

Here’s a good one from a few years back. [Muranushi] built a scanner to automatically scan an entire book. LEGO is used as the primary building material. A book is placed on a LEGO balance (inset photo) with a counterweight that eases the work of raising and lower the book. The book is lowered, a LEGO carriage moves across the book to turn the page, the book is raised to the glass of an upside-down scanner and scanned into a laptop.

It seems LEGO and imaging devices are a great match. Most of the parts used here are from LEGO Technical set 8485, a set that comes with motors and a motor controller seen above, on the floor behind the computer. We’ve embedded some video after the break of a book in the midst of the scanning process. Continue reading “LEGO Book Scanner” →

How To Download Books From Google

September 9, 2009 by Chris Gilmer 79 Comments

If you want books, but don’t want to pay for them, there is a better way than walking into your local book store and pocketing them. Try grabbing them online, from Google!

Everyone must be aware of the Google Books Library project by now. If you’re not, it’s basically a way for Google to ensure all of the world’s book content is accessible and searchable. Through the Book Project, Google works with libraries to scan and archive their older and out of print materials. Up until recently, viewers of books in the Google Library Project web space were limited to viewing books within the browser. Not any more. Google Book Downloader is a utility that rips books from Google and saves them as PDFs so you can view them with any device or desktop that can view this file format. Using Microsoft’s .NET framework, the Google Book Downloader application allows users to enter a book’s ISBN number or Google link to pull up the desired book and begin a download, fishing off with exporting the file to a PDF. Full setup instructions and download are available on Codeplex.

Kindle 2 Teardown

The people at iFixit have shown that they’re still on top of their game by tearing down the new Kindle 2 eBook reader. The main processor is a 532MHz ARM-11 from Freescale. Interestly, there isn’t any significant circuitry behind the large keyboard; it seems its existence is just to hide the battery.

Arduino Duemilanove

October 19, 2008 by Eliot 7 Comments

The latest generation of Arduino hardware has been released. The Arduino Duemilanove (2009 in Italian) has the same form factor as previous generations. The specs are essentially identical to the Diecimila, but there have been a few changes to the hardware. The power source is no longer chosen using a jumper. A MOSFET and dual OPAMP have been added to the board to automatically selected between USB power and the external plug. Automatic hardware resets are optional now. Next to the USB port are two solder pads labeled RESET-EN. Cut the trace between them to kill the reset. If you ever want it back, just bridge the pads. The hardware was updated to correspond with the release of Arduino cofounder [Massimo Banzi]’s new book.

Covert IPhone Moleskine Case

June 12, 2008 by Eliot 7 Comments

Crafting isn’t really our thing, but just last week we were planning on doing this project. Thanks to the how-to singularity: the longer we wait, the more likely someone else will do our dirty work. The instructions are this:

Cut a hole in a book.
Stick your phone in that book.
Let her open the book.

Wired’s write up has about 600 more words if you need clarification. The ebook on the screen is Cory Doctorow’s Little Brother, so expect to see this on BoingBoing… and again when it’s fan translated into Polish. [bre] made a similar hidden compartment book last Fall for Make’s PDFcast.

In all seriousness, we do enjoy the idea of carrying an innocuous little book around that could be doing some covert WiFi scanning, acting as a mobile accesspoint, or live streaming our location to friends. Unfortunately, since it’s an iPhone, most of this isn’t possible yet; you can’t even voice dial from your headset, while leaving the notebook in your pocket. This case also blurs what is considered rude. Most people would be annoyed if you started txting mid conversation, but people taking notes in Moleskines don’t get the same treatment.
